first it was my home machine, I upgrade to itunes 5, and right at the end of the install, the machine shuts off. Flat out off. I thought it must be me, I have alot of wierd stuff installed, and some Embedded C++ drivers are sketchy.

But at work a guy with a brand new box gets the exact same thing! Don't they test their software? Shutting the entire machine completely off - its not the API call "SystemShutdown" but the power to the system goes off

Anyone have Itunes 4? and what on earth could cause the entire PC to just turn off? SCARY

There's a chance it's conflicting with other cd-burning software on your machine.

hmmmm, If it's crashing at the end of the install I'd say it's not a conflict with the CD-burning software.

Might be a bug with the install program. I don't remember which one they use. Looks like they are working on a fix though. Googling for
"install program itunes 5 crash" brings back a lot of hits.

I didn't have a problem during my iTunes 5 install and I haven't had any problems with the playlists or library. But I have had some weird crashes related to multimedia. Not sure if they are iTunes related though.

Don't ya wish there was something in the bios that would detect a frozen OS and dump out the memory to HD or flash memory somewhere for you?

I have an issue with iTunes when running CD Creator at the same time (and using it to burn CDs). I hit the "burn cd" icon accidentally. It hung, and I had to reboot the PC. I figured it was the iTunes drivers vs the CD Creator drivers fighting over the
hardware.

Perhaps the iTunes installer tries to install its drivers at the end of its installation, and that part fails because it's conflicting with existing drivers.

Just an idea.

Are you upgrading a previous version of iTunes? You could uninstall it first. Are you running another CD-buring program? Can you disable it beire you install iTunes 5? Do you get anything in your event log? Try running sysinternal's debugout program while you
install. You might get some interesting messages.

I havent had this problem, the only Application that gives me probs is Firefox 1.0.6 on my Tabet, it keeps crashing and sometimes freezes up the system. I quit using Firefox and went to Maxthon, it works and looks great. I heard about Maxthon from my
sons school librarian , she uses it on the school systems.
